The parasympathetic nervous system is the key to calming anxiety and getting that heart rate back down – but when you’re in the midst of stress and chaos, it can be hard to achieve those peaceful feelings. The good news is, there are a few simple techniques that can trigger this system in a matter of moments.

The parasympathetic nervous system is one of the two main divisions of the autonomic nervous system, which controls involuntary functions in the body. It plays a crucial role in maintaining balance and regulating various bodily processes, especially during times of rest, relaxation, and recovery. Often referred to as the "rest and digest" system, the parasympathetic nervous system counterbalances the "fight or flight" response of the sympathetic nervous system.

Take a look at some of the functions of this system:

• Heart Rate Regulation: The parasympathetic nervous system slows down the heart rate. This is particularly evident when you're in a state of rest, relaxation, or sleep.
• Digestion: It promotes digestion and nutrient absorption by increasing activity in the digestive organs. Blood flow to the digestive tract increases, allowing for efficient digestion and nutrient extraction.
• Pupil Constriction: The parasympathetic system causes the pupils of the eyes to constrict, which is more beneficial for activities in well-lit environments.
• Salivation: It stimulates salivary gland activity, promoting the production of saliva, which is important for beginning the process of digestion in the mouth.
• Bronchoconstriction: It constricts the bronchioles in the lungs, reducing airway diameter. While this might seem counterintuitive, it actually helps in controlling the flow of air and preventing excessive air exchange during periods of rest.
• Blood Pressure Regulation: The parasympathetic system helps regulate blood pressure by relaxing blood vessels and promoting normal blood flow.
• Bladder and Bowel Function: It stimulates the bladder to contract and empty, while also facilitating bowel movements.
• Relaxation and Recovery: Overall, the parasympathetic nervous system promotes relaxation, recovery, and energy conservation. It supports bodily functions that are important during restful periods.

Activities that stimulate the parasympathetic nervous system include deep breathing, meditation, mindfulness practices, progressive muscle relaxation, gentle stretching, and engaging in activities that promote calm and relaxation. Both the sympathetic and parasympathetic nervous systems work together to maintain homeostasis, or balance, in the body. When these systems are in harmony, they help ensure that the body responds appropriately to various situations, whether it's facing a stressor or recuperating during periods of rest. Stimulating the parasympathetic nervous system can help induce relaxation, reduce stress and promote a sense of safety. Here are three effective ways to activate the parasympathetic nervous system:

Deep Breathing

Engage in slow, deep, and controlled breathing. Inhale deeply through your nose, allowing your abdomen to expand. Exhale slowly through your mouth. Focus on extending the exhale phase, as a longer exhale can trigger the relaxation response. You can also practice breath awareness, simply paying attention to your breath without trying to change it. This mindful breathing promotes relaxation and a calm mind. 

Progressive Muscle Relaxation

This technique involves sequentially tensing and relaxing different muscle groups in your body. By doing so, you release physical tension and signal to your body that it's time to relax. This practice can effectively trigger the parasympathetic response. Keen to reap the benefits of this simple practise? We’ve got you covered – here’s a step-by-step guide to winding down and relaxing.

1. Find a Quiet Space: Choose a quiet and comfortable space where you won't be disturbed. Sit or lie down in a relaxed position.
2. Breathing: Begin with a few deep breaths to help you settle into a relaxed state. Inhale deeply through your nose, and exhale slowly through your mouth.
3. Focus on Muscle Groups: Start from your toes and work your way up to your head, progressively focusing on different muscle groups.
4. Tensing Phase: For each muscle group, tense the muscles as tightly as you comfortably can. Hold the tension for about 5-10 seconds, then release. Focus only on the muscles you're tensing, and let the rest of your body remain relaxed.
5. Release Phase: After holding the tension, release the muscles suddenly. Pay attention to the sensation of relaxation as the tension fades away.
6. Focus on Sensations: As you release each muscle group, focus on the sensations of relaxation and comfort. Allow any tension or stress to melt away.
7. Muscle Groups to Target: Progress through the major muscle groups in the body, typically in the following order:

• Toes and feet
• Calves and thighs
• Hips and buttocks
• Abdomen
• Chest and back
• Shoulders and arms
• Hands
• Neck and face

8. Move Slowly: Take your time as you move from one muscle group to the next. Focus on each group individually, ensuring that you fully release tension before moving on.
9. Breathe: Throughout the exercise, maintain slow and deep breathing. Inhale as you tense the muscles, and exhale as you release the tension.
10. Complete the Cycle: Once you've gone through all the major muscle groups, take a few moments to experience the overall sense of relaxation in your body.
11. Return to Normal: Slowly bring your awareness back to the present moment. Gently move your fingers and toes, and open your eyes if they were closed.

Remember that the goal of PMR is to promote relaxation and reduce tension. It's important to focus on the sensations of relaxation during the release phase of each muscle group. Regular practice of PMR can help you become more aware of physical tension and provide you with a valuable tool for managing stress and promoting relaxation in your daily life.

Mindfulness and Meditation

Engaging in mindfulness or meditation practices helps shift your focus away from stressors and into the present moment. These practices often involve deep, mindful breathing and encourage relaxation. Guided imagery meditation, where you visualise a calming scene, can also stimulate the parasympathetic nervous system. Regular mindfulness or meditation sessions can lead to long-term improvements in relaxation response.

It's important to note that the effectiveness of these techniques can vary from person to person. You might find that one technique works better for you than others. Experiment with these practices and find the ones that resonate with you. Consistency is key - incorporating these practices into your daily routine can lead to lasting benefits for your overall wellbeing.
